How useful is this? The Quantum Converter facility increases mineral production in the base where it's built by 50%. Each costs 200 mineral units to build plus 5 per turn to maintain, so the Singularity Inductor is a steal at the cost of only about 2.5 Quantum Converters. No other Project in SMAC has such a radical effect on your faction's productivity. Production underlies military might (building military units), territorial expansion (building colony pods), and base development (building base facilities). I consider this the last (and among the most desirable) midgame Projects before the endgame's Voice of Planet and Ascent to Transcendence.
